jamming gears

I went on a little road trip with a friend of mine this weekend. I was driving my '00 Z-28 M6 with NO mods, he was driving his '01 Mustang GT w/ Vortech supercharger, shorty headers, cat back and I don't know what else. Anyway, we were having a good time screwing around on the road. I was rather surprised to find out that he can't run from me. At 75 we both went down to fourth and stood on it. I thought he'd be pulling from me. Nope. We were door to door and I had two gears left when we approached traffic.

My biggest concern is this, at 120 I can't get the damn thing into 5th. I can go to 6th with no issue. But, I can't get into 5th. I tried everything. I tried jamming it in, easing it in, and double clutching. Hell, I was ready to buy it a drink and bust out the KY. It just wouldn't go. Anyone else had this issue?

sucks that no one has an answer to your 5th gear though? it couldn't be the synchro could it? i mean, that is an over-drive gear, the sycnch should mesh like hot knife through butter

It could be a synchro issue I s'pose. The thing that bothers me about it is this, why does it shift fine whenever I'm not in the top of my RPM's in fourth? Whenever I get near redline in fourth and try to go to 5th the problem kicks in. No other time.

It could be a synchro issue, but why wouldn't it be a problem any other time?

do you have the shift skip eliminator? under certin rpms and loads it will make you skip a gear. like if you get on it and wind it out in first it will make you shift to 4th. if you dont try this. http://www.slponline.com/view_product.asp?P=21008
